This is happening on Agrarian 2, I have not attempted it on other servers yet. Whenver I enter the /ticket command, it tells me a pre-login is required, but I'm already logged in on the ticket site. I have tried logging out and doing the command, as well as logging back in, but it does not work. For the time being, I'll just post any problems I get to the Support subforum, but I'm hoping that this can be fixed.
